Technical Field

[0001] This utility model relates to the field of peanut planting equipment technology, and in particular to a peanut quantitative planting device. Background Technology

[0002] Peanuts are an important oilseed and cash crop in my country, with a wide planting area. The efficiency and quality of planting operations directly determine the yield and quality of peanuts. Currently, peanut planting mainly relies on two modes: manual planting and traditional mechanical planting, but both have obvious drawbacks.

[0003] However, while traditional mechanical seeding devices can improve efficiency to some extent, their core performance still has many shortcomings: insufficient quantitative accuracy. Existing devices mostly use simple grooved wheel or spoon-type seed metering structures, lacking precise material control components. They cannot flexibly adjust the quantitative specifications according to the size of peanut seeds, resulting in large deviations in the seeding amount between different batches, which affects the consistency of subsequent growth. Therefore, a peanut quantitative seeding device is proposed. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing a peanut quantitative planting device.

Three sets of support frame plates 6 are installed at one end of material box 2.

[0019] The specific setup and function of this embodiment are described below. The frame 1 serves as the installation foundation for the entire device. It is constructed from high-strength angle steel to form a frame structure, ensuring overall structural stability and enabling it to bear the weight of all components, including the material box 2 and transmission parts. It also provides precise installation positioning references for each component. A horizontal support plate is welded to the middle of the frame 1 for installing the unloading head 3 and related transmission parts. The support plate is reinforced to enhance its load-bearing capacity. The material box 2 is made of stainless steel sheet, stamped into a hollow rectangular structure with an open top, providing excellent corrosion resistance. The device is corrosion resistant and has structural strength, capable of holding a sufficient amount of peanut seeds to meet the needs of continuous sowing. The feed box 2 is fixedly installed at the upper middle position of the frame 1 by bolts. The bottom of the feed box 2 is equipped with an inclined seed guide plate. The angle between the seed guide plate and the bottom of the feed box 2 is set to 30-45°, which can guide the seeds to slide naturally to the feed pipe 9 position, avoiding the accumulation and blockage of seeds in the feed box 2. Three sets of support frame plates 6 are fixedly installed at one end of the feed box 2. The support frame plates 6 are made of steel plate and are used to assist in supporting the feed box 2 and stabilizing the transmission components, further improving the overall stability of the device.

[0020] L-shaped frames 4 are symmetrically installed on both sides of the material box 2. The L-shaped frames 4 are made of angle steel and are fixedly connected to the side wall of the material box 2 by welding. The connection part is reinforced with reinforcing ribs. A rotating shaft 5 is rotatably installed through the end of each set of L-shaped frames 4 away from the material box 2. The rotating shaft 5 is made of high-strength round steel and is rotated with the L-shaped frames 4 through bearings at both ends to ensure smooth rotation. Ground wheels 7 are fixedly installed on the outer wall of each set of rotating shafts 5. The ground wheels 7 are made of rubber and have anti-slip texture on the outer circumference to increase the friction with the ground, improve the stability of the device during movement, and reduce damage to the soil surface.

[0021] The lower end of the feed box 2 corresponds to the sowing row spacing requirement, and multiple sets of feed pipes 9 are installed through it. The feed pipes 9 are made of hard plastic, and the upper end is welded and fixed to the bottom of the feed box 2. The lower end of each set of feed pipes 9 is fixed to the feed control seat 10 by a flange. The feed control seat 10 is made of aluminum alloy and has a hollow cavity structure inside, which is used to install the rotating column 15 and realize the quantitative distribution of seeds. The lower end of the support plate in the middle of the frame 1 corresponds to the position of the feed pipes 9, and multiple sets of feed heads 3 are installed through it. The feed heads 3 are conical tubular structures made of stainless steel, which are easy to insert into the soil to complete the sowing.

[0022] Multiple sets of material control seats 10 are each rotatably mounted with a rotating column 15 at one end. The rotating column 15 is made of high-strength nylon and its outer surface is smoothed to reduce friction with the inner wall of the material control seat 10. A quantitative groove 18 is opened through one end of each set of rotating columns 15. The quantitative groove 18 is an arc-shaped groove structure. According to the common peanut planting requirements, three sets of mating seats 16 are fixedly installed at the lower end of the material box 2. The mating seats 16 are symmetrically distributed. A long rod 17 is rotatably mounted inside the three sets of mating seats 16. The long rod 17 is made of round steel and provides an installation base for adjusting the material control block 21.

[0023] The outer wall of the long rod 17 corresponds to the position of each set of control seats 10, and multiple sets of connecting plates 19 are fixedly installed. The connecting plates 19 are made of stamped steel plates and are fixedly connected to the long rod 17 by bolts. The inner wall of each set of connecting plates 19 is fixedly installed with a fixed round seat 23. The fixed round seat 23 adopts a bearing structure design. One end of each set of fixed round seats 23 is rotatably installed with a rotating round plate 22, which can rotate flexibly around the fixed round seat 23. One end of each set of rotating round plates 22 is fixedly installed with multiple sets of control blocks 21. The control blocks 21 are made of elastic rubber and their shape is adapted to the quantitative trough 18. A part of each set of control blocks 21 is slidably set inside the multiple sets of quantitative troughs 18, which can sort and limit the seeds in the quantitative trough 18 to ensure accurate seed dispensing each time.

[0024] A threaded seat 20 is fixedly installed at the lower end of the feed box 2 near the end of the long rod 17. The threaded seat 20 is made of cast iron and has precision threads inside. A connecting rod 25 is rotatably installed at one end of the long rod 17 via a pin. A hexagonal bolt 24 is threadedly connected to one end of the threaded seat 20. The other end of the connecting rod 25 is fixedly connected to one end of the hexagonal bolt 24 by welding. By rotating the hexagonal bolt 24, the connecting rod 25 can be driven to push the long rod 17 to move. In turn, the fixed round seat 23 and the rotating round plate 22 are adjusted through the connecting plate 19, so as to realize the adjustment of the insertion depth of the control block 21 in the quantitative groove 18, meet the quantitative requirements of peanut seeds of different sizes, and further control the feeding amount. At the same time, multiple sets of fixed round seats 23 and multiple sets of rotating round plates 22 are rotatably installed on the rotating rod 11 to ensure that the rotation of the rotating rod 11 can synchronously drive the rotating column 15 to rotate, so as to realize continuous seed dispensing.

[0025] The lower ends of multiple sets of material control seats 10 are all fixedly connected to folded tubes 12. The folded tubes 12 are made of expandable corrugated rubber tubing, which has good flexibility and wear resistance, and can be flexibly extended and retracted according to the sowing depth requirements. The lower parts of the multiple sets of folded tubes 12 are respectively inserted into the interiors of multiple sets of feeding heads 3. The feeding heads 3 and the folded tubes 12 are in a sliding fit. By adjusting the installation height of the feeding heads 3 on the support plate of the frame 1, or by utilizing the expansion and contraction characteristics of the folded tubes 12, different sowing depth requirements can be quickly adapted, improving the adaptability of the device to different planting scenarios.

[0026] Example 2: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, large pulleys 8 are fixedly installed on the outer walls of both sets of rotating shafts 5, and small pulleys 13 are fixedly installed on the outer walls of rotating rods 11. Two sets of transmission belts 14 are installed on the outer walls of the two sets of large pulleys 8 and the two sets of small pulleys 13.

[0027] The overall effect of this embodiment is as follows: a rotating rod 11 is rotatably installed at the middle position of the two sets of L-shaped frames 4. The rotating rod 11 is made of seamless steel pipe, and its length is adapted to the width of the frame 1. Both ends are rotatably connected to the L-shaped frame 4 through bearing seats. Large pulleys 8 are fixedly installed on the outer walls of the two sets of rotating shafts 5 near their ends. Small pulleys 13 are fixedly installed on the outer walls of the rotating rod 11 at the positions corresponding to the large pulleys 8. Both the large pulleys 8 and the small pulleys 13 are made of cast iron and have been treated with anti-rust coating. Two sets of transmission belts 14 are respectively installed on the outer walls of the two sets of large pulleys 8 and the two sets of small pulleys 13. The transmission belts 14 are made of wear-resistant rubber to ensure the stability of power transmission. Through the cooperation of the large pulleys 8 and the small pulleys 13, the rotational power of the ground wheel 7 can be accurately transmitted to the rotating rod 11, realizing the synchronous linkage between the movement of the device and the seeding action.

[0028] The usage method and working principle of this device are as follows: First, when the device is driven forward by the external traction equipment, the rotating shaft 5 on the L-shaped frame 4 on both sides of the frame 1 rolls with the ground and drives the ground wheel 7 to rotate. The large pulley 8 on the rotating shaft 5 drives the small pulley 13 on the rotating rod 11 to rotate through the transmission belt 14, so that the rotating rod 11 rotates synchronously, realizing the linkage between the power of movement and seeding. Afterwards, the peanut seeds in the feed box 2 slide into the feed pipe 9 through the inclined seed guide plate and enter the control seat 10; the rotating rod 11 rotates, driving the fixed round seat 23 and the rotating round plate 22 sleeved on it to rotate, which in turn drives the rotating column 15 to rotate, and the quantitative groove 18 on the rotating column 15 receives the seeds as it rotates; the control block 21 on the rotating round plate 22 extends into the quantitative groove 18 to scrape off excess seeds to achieve quantitative measurement, and then when the quantitative groove 18 containing the quantitative seeds rotates to the bottom, the seeds fall into the folded tube 12; Then, rotate the hexagonal bolt 24 on the threaded seat 20, and pull the long rod 17 along the mating seat 16 through the connecting rod 25. The long rod 17 drives the connecting plate 19 to adjust the position of the fixed round seat 23, so that the insertion depth of the control block 21 in the metering groove 18 changes to adapt to the metering requirements of seeds of different particle sizes. Finally, the folding tube 12 introduces a quantitative amount of seeds into the feeding head 3, which is then inserted into the soil to complete the sowing. The folding tube 12 can be flexibly extended and retracted, and its installation height on the support plate of the feeding head 3 on the frame 1 can be adjusted to achieve different sowing depths. The support plate 6 at one end of the material box 2 enhances the overall structural stability and ensures smooth continuous operation.
